CNRM-CERFACS CNRM-CM6-1 model output prepared for CMIP6 LS3MIP amip-lfmip-rmLC

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.LS3MIP.CNRM-CERFACS.CNRM-CM6-1.amip-lfmip-rmLC' with the full Data Reference Syntax following the template 'mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version'. The CNRM-CM6-1 climate model, released in 2017, includes the following components: aerosol: prescribed monthly fields computed by TACTIC_v2 scheme, atmos: Arpege 6.3 (T127; Gaussian Reduced with 24572 grid points in total distributed over 128 latitude circles (with 256 grid points per latitude circle between 30degN and 30degS reducing to 20 grid points per latitude circle at 88.9degN and 88.9degS); 91 levels; top level 78.4 km), atmosChem: OZL_v2, land: Surfex 8.0c, ocean: Nemo 3.6 (eORCA1, tripolar primarily 1deg; 362 x 294 longitude/latitude; 75 levels; top grid cell 0-1 m), seaIce: Gelato 6.1. The model was run by the CNRM (Centre National de Recherches Meteorologiques, Toulouse 31057, France), CERFACS (Centre Europeen de Recherche et de Formation Avancee en Calcul Scientifique, Toulouse 31057, France) (CNRM-CERFACS) in native nominal resolutions: aerosol: 250 km, atmos: 250 km, atmosChem: 250 km, land: 250 km, ocean: 100 km, seaIce: 100 km. Project: These data have been generated as part of the internationally-coordinated Coupled Model Intercomparison Project Phase 6 (CMIP6; see also GMD Special Issue: http://www.geosci-model-dev.net/special_issue590.html). The simulation data provides a basis for climate research designed to answer fundamental science questions and serves as resource for authors of the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC-AR6). CMIP6 is a project coordinated by the Working Group on Coupled Modelling (WGCM) as part of the World Climate Research Programme (WCRP). Phase 6 builds on previous phases executed under the leadership of the Program for Climate Model Diagnosis and Intercomparison (PCMDI) and relies on the Earth System Grid Federation (ESGF) and the Centre for Environmental Data Analysis (CEDA) along with numerous related activities for implementation. The original data is hosted and partially replicated on a federated collection of data nodes, and most of the data relied on by the IPCC is being archived for long-term preservation at the IPCC Data Distribution Centre (IPCC DDC) hosted by the German Climate Computing Center (DKRZ). The project includes simulations from about 120 global climate models and around 45 institutions and organizations worldwide. - Project website: https://pcmdi.llnl.gov/CMIP6.

耦合模型比较计划第六阶段（Coupled Model Intercomparison Project Phase 6，CMIP6）数据集：此类数据集涵盖所有以'CMIP6.LS3MIP.CNRM-CERFACS.CNRM-CM6-1.amip-lfmip-rmLC'标识发布的数据集，且严格遵循完整数据参考语法模板'mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version'。本次使用的CNRM-CM6-1气候模式于2017年正式发布，其组成模块如下：气溶胶模块采用TACTIC_v2方案计算得到的逐月强迫场；大气模块为Arpege 6.3（T127格型；采用高斯缩减格网，总计24572个格点，分布于128条纬度圈：南北纬30°区间内每条纬度圈包含256个格点，向南北纬88.9°处逐步缩减至每条纬度圈20个格点；共设置91层垂直结构，顶层高度达78.4 km）；大气化学模块为OZL_v2；陆面模块为Surfex 8.0c；海洋模块为Nemo 3.6（采用eORCA1三极坐标格网，核心分辨率为1°；经纬度格点尺寸为362×294；共75层垂直结构，顶层网格水深范围为0~1 m）；海冰模块为Gelato 6.1。该模式由法国国家气象研究中心（Centre National de Recherches Meteorologiques，图卢兹31057，法国）与欧洲科学计算高级研究与培训中心（Centre Europeen de Recherche et de Formation Avancee en Calcul Scientifique，图卢兹31057，法国，合称CNRM-CERFACS）以原生名义分辨率完成运行，各模块分辨率分别为：气溶胶模块250 km，大气模块250 km，大气化学模块250 km，陆面模块250 km，海洋模块100 km，海冰模块100 km。本数据集作为国际协调开展的耦合模型比较计划第六阶段（CMIP6；详见《Geoscientific Model Development》特刊：http://www.geosci-model-dev.net/special_issue590.html）的核心产出成果生成。该模拟数据可为解答气候科学核心问题的研究提供数据支撑，同时作为政府间气候变化专门委员会第六次评估报告（IPCC-AR6）作者群体的重要参考资源。CMIP6项目由世界气候研究计划（World Climate Research Programme，WCRP）下属的耦合建模工作组（Working Group on Coupled Modelling，WGCM）负责协调推进。第六阶段继承了此前由气候模型诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导开展的多轮多模式对比实验，并依托地球系统网格联盟（Earth System Grid Federation，ESGF）、环境数据分析中心（Centre for Environmental Data Analysis，CEDA）及众多相关协作活动完成项目落地实施。原始数据存储于分布式数据节点联盟中并实现部分镜像复制；IPCC评估报告所依赖的绝大多数数据集，将由德国气候计算中心（German Climate Computing Center，DKRZ）托管的IPCC数据分发中心（IPCC Data Distribution Centre，IPCC DDC）进行长期归档保存。该项目汇聚了全球约120个全球气候模式与近45家科研机构及组织的模拟实验成果。项目官网：https://pcmdi.llnl.gov/CMIP6。
